SPRING OILER.

Applicatioirfiled September 11, 1923. Serial No. 662,056.

To all whom it may concern.

Be it known that 1, WILLIAM S. SrLvirsran, a citi Zen of the UnitedStates, residing at Denver, in the city and county of Denver, and Stateof Colorado, have invented certain new and useful Improvements in SpringOilers; and I do declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to use the sa which it appertains to make and me, reference beinghad to the accompanying drawings, and to the characters of referencemarked thereon, which form a part of this specification.

This invention relates to a device for oiling automobile springs.

Springs, such as are ordinarily employed in connec types of tion withautomobiles and other vehicles, are almost invariably formed from aplurality of springs assembled in superposed relation with each leafshorter th an the adjacent longer leaf. Such a spring is usuallydesignated as a multiple leaf sprin and owes its flexibility to thenature of the material employed and to the fact that the s vei'al leaveshave a sliding motion with resp ect to each other. If the several leaveswere connected in such amanner that they were not relatively slidable,then the spring would be stiff and unyielding, being in effect amultiple 1 solid bar of steel. Tn order that a eaf spring shall functionproperly,

the leaves must be freely slidable and this they can only do by beingproperly lubriis difficult to lubricate a multiple leaf spring and forthat reason very few springs re ceive any lubrication whatever and leafsprin g, and which will keep the spring properly lubricated at alltimes.

My invention can be most clearly explained by reference to theaccompanying drawing in which the preferred embodiment thereof is shown,and in which:

Fig. 1 shows a side elevation of an elliptical spring to which myimproved oiler has been applied;

Fig. 2 is a section taken on line E .2, Fig.

is a section taken on line 3-3 The same reference characters will beemployed to designate the same parts throughout the several views.

Numeral 1 designates the upper half and 2 the lower half of anelliptical multiple leaf spring. Each half has a master leaf 3 and aplurality of auxiliary leaves 43 which are progressively shorter thanthe master leaf. The several leaves are held together by clamps 5 andsometimes by central bolts (not shown). At various points along thespring there are clamps 6 which hold the leaves in alignment. Myimproved oiler consists of a member 7 of sheet metal bent into channelshape in the manner shown in Fig. 3. The sides 8 are slightly wider thanthe thickness of the spring at the point where they are applied and areperforated for the reception of a. clamping bolt 9. The length of theoiler may be determined by the construction of the spring to which it isapplied, but is preferably four inches. Extending transversely throughthe oiler near the bottom portion thereof is a flattened tubular memberlO which has its narrow sides perforated in the manner indicated bynumerals 11. The flattened member 10 is formed from a pipe, a portion 12of which is left circular and extends diagonally from the oiler in themanner clearly shown in Fig. 3. A spring oil cap 13 is secured to theend of the pipe 12 and serves to exclude the dust and dirt. A piece ofthick rubbing felt 14 is placed in the bottom of the oiler and restsupon the spring when the oiler is in place thereon. Extending from oneend of the bottom portion 7 is a projection 15 which is adapted to beinserted into the space between the surface of the spring and the insideof the clamp 6 in the manner shown in Fig. 2. This serves to prevent theoiler from sliding along the spring surface. The pipe 12 is usuallyconnected to the oiler near the end of the oiler furthest from theprojecting portion 15. When the oilers are applied to the springs theyare secured thereto at the highest point to which they can beconveniently connected. On the upper half of the spring the oilers aresecured near the center and on the lower half near the ends, all asshown in Fig. 1. The oilers are so constructed and arranged that thepipe 12 is at the highest end of the oiler.

When the oiler is in place on the spring, as shown in Fig. l, and oil isintroduced into the pipe 12, the felt 14; will become saturated with oiland as the spring flexes, some of this oil will be squeezed out and flowdown over the sides of the leaves. The oil will penetrate between theleaves, due to the capillary action, and as the oilers are located atthe highest point or points of the springs, the oil will flow downwardlybe tween the leaves and thereby keep the entire spring leaf surfacesproperly lubricated.

From the above, it will be apparent that I have invented a simple springoiler that can be applied to any multiple leaf spring and which willkeep the same properly lubricated at all times.

Having now described my invention, what I claim as new is:

' 1. A spring oiler comprising a channelshaped member of sheet metal,one end of the bottom of said member being longer than the sides, a pipehaving one end flattened, said flattened end projecting through theoiler near the bottom thereof, a piece of felt within said member, andmeans for clamping the member to a spring.

2. A spring oiler comprising in combination, a body member of sheetmetal bent into a U-shaped cross-section, said member having a bottomand two sides, a flattened tubular member extending through the bodymember near the bottom thereof, said tubular member having one endcylindrical, said cylindrical end projecting outwardly from the bodymember and being angularly inclined with respect to the sides thereof,said sides being provided with openings for the reception of a clampingbolt.

3. A spring oiler comprising, in combination, a body member of sheetmetal bent into a U-shaped cross-section, said member having a bottomand two sides, a flattened tubular member extending through the bodymember near the bottom thereof, said tubular member having one endcylindrical, said cylindrical end projecting outwardly from the bodymember and being angularly inclined with respect to the sides thereof,said sides being provided with openings for the reception of a clampingbolt, the bottom member having one end thereof extending beyond the endsof the sides.

4. A spring oiler comprising, in combination, a body member of sheetmetal bent into a U-shaped' cross-section, said member having a bottomand two sides, a flattened tubular member extending through the bodymember near the bottom thereof, said tub-ular member having one endcylindrical, said cylindrical end projecting outwardly from the bodymember and being angularly inclined with respect to thesides thereof,said sides being provided with openings for the reception of a clampingbolt, the bottom member having one end thereof extending beyond the endsof the sides, and a piece of absorbent felt in the bottom of said bodymember.

In testimony whereof I affix my signature.

WILLIAM S. SYLVESTER.
